摘要
介绍了永磁同步电机伺服系统电流环仿真模型的建立方法。通过数字仿真探讨了伺服系统电流环调节器参数的设计和调整,研究了电流微分反馈对电流环动态过程响应的改善,分析了电流微分反馈强度的设置。考虑到电流环的简化,分析了将电流环近似等效为一阶惯性环节的可行性,并讨论了所设计系统电流环的稳定性。
The method modeling of PMSM current loop simulation was introduced. Based on numeric simulation, the design and adjust of the servo system current regulator parameters were discussed, and the improvement of current differential coefficient feedback on current dynamic response, the setup of current differential coefficient feedback were analyzed. The feasibility of current loop equivalent to one order inertia model was studied to simplify current loop for analyzing speed loop, and the stability of current loop was discussed.
